No IPv6 Support here yet…two of our equipment vendors have been promising it for three
years now – finally vendor1 has started putting out beta firmware and vendor2 is probably
still a year away.
Once its out of beta, I am planning on tunnelling the traffic as v4 through vendor2’s
equipment and releasing it back out the upstream sides as v6 so its transparent to the end
user, but adds a bit of overhead to packets flowing through the core.
Not sure what size subnets we will use – from the light reading I have done on the subject
so far, there is a standardised or suggested size for isp subscribers.

Subject: [nznog] IPv6 support across NZ ISPs
After last year's IPv6 issues, I was wondering what the status is of IPv6 support
across NZ ISPs. I couldn't find that data in any one place, so I've been pulling
it together myself, into a Google Sheet:
This is primarily focused around residential ISPs, and the status of their IPv6 support
for 'regular' customers. I'm interested in three things:
* Is IPv6 supported - fully or trial?
* What prefix lengths are given to customers
* Are static allocations available?"
I've got data on 11 ISPs so far, with requests out for another 3. This covers the
majority of end-user connections in NZ. There are of course many more niche ISPs, and
I'm happy to add their info. You can see that support is generally poor, which is
probably why Google says we're only doing ~0.6% IPv6 traffic.
Comments + Updates welcome. Once I've got a bit more data, this will probably go into
a more permanent home. If we get enough data, we could break out into residential vs
business vs co-location IPv6 support.
I am aware of at least a couple of ISPs that are doing IPv6 trials, and when they go live,
it will significantly shift the overall IPv6 penetration rate in NZ. But those trials are
still mostly internal only, and you can only get on them if you know the right people. If
the regular public can't get onto those trials, then I think they should be listed as
"Unsupported" - too many ISPs have made noises about running trials years ago,
but never got around to actually launching. You know who you are.
